IBN SAHL, ABU OMAR JOSEPH BEN JACOB:

Poet and scientist; died at Cordova 1124. He was a pupil of Isaac ibn Ghayyat, was rabbi at Cordova for nine years, and was distinguished for both learning and piety. Joseph ibn Sahl, who must not be confounded with the poet Joseph ibn Suli, is counted by Al-Ḥarizi among the foremost poets of his time; though his verse is without any peculiar elegance, it is easy and fluent. He was intimately acquainted with Moses ibn Ezra, who addressed several poems to him.
